Rolled tubes can undergo various complex deformations and deep mechanical processing

       Rolled pipe is a precision steel pipe material that has been processed by cold drawing or hot rolling. It has high dimensional accuracy and can be used for various complex deformations and deep mechanical processing. The smaller the outer diameter, the higher the precision and can be used for small batch production.
       For mass productionRolled tubeIn terms of quality, it is necessary to ensure quality, and to ensure quality, real-time online monitoring of quality conditions is required, and measuring instruments are required to achieve this. In order to ensure the quality of steel pipes, online measuring equipment is used, and its measurement accuracy can reach 0.02mm.
       The surface quality of the rolled tube is good. Its surface is cross-textured, which is beneficial to the storage of lubricating oil and the maintenance of oil film. It has a high surface bearing ratio (the ratio of the actual contact area between the hole and the shaft to the mating area between the two), so it can withstand larger loads and resist wear, thereby increasing the service life of the product. The honing speed is low, and the whetstone and the hole are in surface contact, so the average grinding pressure of each abrasive grain is small. In this way, the heat generated by the workpiece is very small during honing, and the surface of the workpiece is basically free of thermal damage and deterioration layers, and the deformation is small. There is basically no embedded sand and extruded hard layer on the honed surface.
